Preliminary results from sun photometer CIMEL CE-318 measurements over Camagüey, Cuba, are reported. The instrument belongs to the Iberian Network for Aerosol Measurements (RIMA). The dataset, at the 1.5 level of Aerosol Robotic Network (AERONET), covers the period between October 7th, 2008 and March 29th, 2009. Obtained results, considered as background conditions, allow characterizing the aerosols over Camagüey as Maritime Mixed. Main results showed the average value of the aerosol optical thickness: τa(500 nm)=0.11 and its mode value at τam(500 nm)=0.11 while for the Ångström exponent the average was α=0.87 with mode value of αm=0.70. Relatively high values in both parameters for marine aerosols, agree with reported values by other studies for maritime environments in the Atlantic ocean. A preliminary characterization about aerosol particles size distribution over Camagüey has been conducted. Arrival of Saharan dust layers to our territory, is evident in several episodes that have taken place during the month of July 2009, with an aerosol optical thickness maximum value of τa(500)=0.70 on July 6th. © Sociedad Española de Óptica.
